CLEVIS.

SPECIFICATION forming part of Letters Patent No. 683,722, dated October 1, 1901.

Application filed June 5, 1901.

T0 at whom it may concern.-

Be it known that I, WILLIAM O. BERRY, a citizen of the United States, residing at Caro, in the county of Tuscola, State of Michigan, have invented certain new and useful Improvements in Olevises; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to a clevis; and it consists in the construction and arrangement of parts hereinafter fully set forth, and pointed out particularly in the claims.

The object of the invention is to produce a clevis of simple and inexpensive construction in which the arrangement is such as to provide for locking the clevis-pin to prevent its accidental withdrawal from the clevis, obvi ating the threading of the clevis-pin and the using of a nut or bur thereon, as ordinarily practiced.

The above object is attained by the construction illustrated in the accompanying drawings, in which-- Figure 1 is a perspective view of my improved clevis. Fig. 2 is a side elevation thereof, showing by dotted lines the movement of the locking-spring. Fig. 3 is a longitudinal section on line 3 3 of Fig. 2. Fig. 4 is a transverse section on line 4. 4 of Fig. 2. Fig. 5 is an elevation of the clevis-pin.

Referring to the characters of reference, 1 designates the clevis, which is formed of wrought iron or steel and provided with the usual parallel sides, in which are formed the registering keyhole-openings 2. The larger portion of these openings is adapted to freely receive the clevis-pin 3, which is adapted to be passed therethrough. Formed in the opposite ends of the clevis-pin are parallel channels 4; of sufficient width to receive the thickness of the sides of the clevis. The reduced portion 5 of the keyhole-openings is onlylarge enough to receive the reduced portion of the clevis-pin lying between the chan nels 4:, so that when inserting the clevis-pin after it is passed through the larger openings Serial No. 63,198. (No model.)

it must be turned until the channels 4 therein register with the sides of the reduced or slotted portion of the openings 5, when the pin may be moved forward into the extreme outer ends of said openings, wherein it is securely confined by the sides of the clevis lying in the channels 4 and is thereby held from m tation.

To prevent the clevis-pin from working back into the larger portion of the keyholeopenings, a spring 6 is pivoted at 7 to one of the sides, and the free end thereof is bent downwardly, so as to lie in one of the openings 2 and project into the reduced portion 5 thereof in proximity to the clevis-pin therein, whereby any backward movement of said pin is prevented. When it is desired to'remove the pin, the free end of the spring is forced out ofthe openings 2 and swung around, as shown by dotted lines in Fig. 2, when the clevis-pin may be moved backward into the openings 2 and withdrawn from the clevis. By this arrangement a clevis-pin may be quickly and firmly secured in place in a manner to obviate wearing said pin and without the expense of threading the end thereof and securing it in place by means of a nut. The arrangement shown not only provides for securing the pin firmly in place, but allows it to be easily and quickly removed when desired.

Having thus fully set forth my invention, whatI claim as new, and desire to secure by Letters Patent, is-

1. A clevis provided with keyhole-openings in its opposite sides, a clevis-pin having fiattened surfaces adapted to lie in the reduced portion of said openings and a movable spring mounted on the clevis having its free end extending into one of said openings in the path of said pin. I

2. A clevis, having openings in the opposite sides thereof, a pin adapted to be passed through said openings one of said openings having a reduced portion adapted to snugly confine the pin and a movable member mounted on the clevis adapted to be moved into said opening in the path of said pin.

3. A clevis, having registering openings in the sides thereof provided with a reduced forwardly-extending portion, a clevis-pin 2 I eyr adapted to pass freely through the larger porto lie in one of said openings and movable tion of said openings and having parallel into and out of the path of said pin. 16 channels in the opposite faces thereof at its In testimony whereof I sign this specificaopposite ends, said channels adapted to retion in the presence of two witnesses.
